First of all,I'm French and forgive me if at some point what I write is not totally clear, I sometimes miss some technical vocabulary…
I'm on the latest version of Wp ,using Itheme security and also Rankmath seo plugin which generates my sitemap
When I submit the sitemap in GSC ,it says, “impossible to get the sitemap” and there is a 403 error code associated .
Is there anyone who could give me a list of things to check to solve this. I'm not a technician so I don't know what to start with.
Thanks a lot for considering my request
